A reward of up to £20,000 has been offered for anonymous information about the attack on former Celtic chief Peter Lawwell’s home.
Crimestoppers has put up the money as they urge people who may know or have suspicions about who carried out the attack in May.
Three vehicles at Lawwell’s house in Thorntonhall were doused in fuel before being set alight in the early hours.
The fire caused significant damage to the garage above which it is understood Lawwell’s daughter and four-month-old granddaughter were sleeping.
CCTV showed a man pouring accelerant onto the vehicles parked in the drive-way of the home.
Mick Duthie, director of operations at Crimestoppers, appealed for anyone with information to speak to them.
“The potential risk to life from this kind of attack means we urgently need anyone with information about those responsible to come forward before someone is seriously hurt,” he said.
“We know it can be difficult to speak up about crime, especially if it’s about someone close to home or because you may be fearful of the consequences.
“However, that’s why Crimestoppers is here for you – to take your information whilst you stay completely anonymous.”
He continued: “Since we began in the late 1980s our charity has always kept its cast-iron guarantee to the hundreds of thousands of Scots who have trusted us with their anonymous information over the years.
“You can use our easy and secure anonymous online form at crimestoppers-uk.org to pass on what you know or you can talk to us by calling our UK Contact Centre which is open 24/7 on freephone 0800 555 111.
“Not only may you be eligible for a reward, but you’ll be doing the right thing.”
